"Businesses will be able to post job openings to a Jobs tab on their Page, Jobs dashboard, Facebook Marketplace, and the News Feed that they can promote with ads. Meanwhile job seekers can discover openings, auto-fill applications with their Facebook profile information, edit and submit their application, and communicate via Messenger to schedule interviews."

This could be a tremendous service to small businesses and entrepreneurs around the world. According to a Facebook official, 40% of them in the U.S. have had problems filling the jobs that were open.

Meanwhile, those of us in the high-skill niche are balking at LinkedIn pricing for a similar service. That's LinkedIn ProFinder. Supposed good fits for our skills arrive in our in-box. The prospective employer or client provides the specs. We respond with a brief proposal and a bid.

I participated in a one-month free trial. The filters were for my general geographical area. Although I submitted a ton of proposals, there was only one positive response. And that was to agree that I was a good fit but too far for an easy commute, so that prospect ruled me out.

After the free trial, the monthly cost is about $60.00. That's way more than my internet service and about $10 more than what I pony up to AT&T for my smartphone connection.

If Facebook can configure a lower-cost approach for professionals like myself and then keep building an ecosystem, LinkedIn could be history. So, might that niche on Craigslist.
